Key result
A single CT slice at the T7 or T8 vertebral level strongly correlates with total chest subcutaneous and visceral adipose tissue volumes (PCC 0.97 and 0.86, respectively) in adult lung transplant candidates.
Why the study?
Can single-slice CT accurately estimate total chest fat volume compared to volumetric CT in lung transplant candidates?
Population
40 adult lung transplant candidates, mean age 58 ± 12 years, mean BMI 26.4 ± 4.3 kg/m2.
Comparison
Chest fat quantification and quality assessment… vs Volumetric CT (whole chest volume).
Design
Cross-sectional

May improve adiposity-based risk stratification in lung transplant candidates beyond BMI; leaves open prospective validation of clinical utility.

Effect estimate: PCC 0.97 for SAT, 0.86 for VAT
Single-slice CT at the T7 and T8 vertebral levels can reliably estimate total subcutaneous and visceral chest fat volume in lung transplant candidates.
Tong et al. (2017) conducted a cross-sectional in Lung transplant candidates (n=40). Single slice CT at T7/T8 vertebral levels vs. Whole chest volumetric CT was evaluated on Pearson correlation coefficient (PCC) between single chest slice fat area and total chest fat volume (PCC 0.97 for SAT, 0.86 for VAT). A single CT slice at the T7 or T8 vertebral level strongly correlates with total chest subcutaneous and visceral adipose tissue volumes (PCC 0.97 and 0.86, respectively) in adult lung transplant candidates.
